"The helicon plasma thruster is an electrodeless system, which allows it to undertake long operations performed at a high-power level. Electron Cyclotron Resonance (ECR) is one of several methods for ionizing and heating a plasma using electromagnetic (EM) waves. Looking for abbreviations of PPT? It is Pulsed plasma thruster. Microplasma thruster for ultra-small satellites: Plasma chemical and aerodynamical aspects* Yoshinori Takao, Takeshi Takahashi, Koji Eriguchi, and Kouichi Ono‡ Department of Aeronautics and Astronautics, Graduate School of Engineering, Kyoto University, Yoshida-Honmachi, Sakyo-ku, Kyoto 606-8501, Japan. They are robust and simple, as they do not have any naked electrodes in contact with the plasma. “It’s the most powerful plasma rocket in the world right now,” says Franklin Chang-Diaz, the former NASA astronaut who heads the company. Analyse, model and simulate plasma production in electric thrusters as Pulse Plasma Thruster, micro Vacuum Arc Thruster, Electrodeless Electric Propulsion, etc. The plasma thruster technology helps with this problem. A version of this seemingly impossible device is used on a larger scale to propel deep space probes for NASA. you need 2 ICRH antennas (i have no idea where you would get thoes) a quartz pipe (good luck) a HIGH amount of hydrogen (is that even legal?) or helium gas.
